Rear Under-Spoiler 2015+ WRX/STI

This rear diffuser/wing spoiler fits underneath the rear valance of the 2015+ WRX and STI. The purpose is to keep air spilling out from under the car from sticking to the back of the car; the spoiler helps the air to stay in a linear stream for as long as possible, reducing drag.

Plus it looks cool.

Kit includes ABS spoiler blade (molded in satin-black, so there's no paint to chip off), plus mounting brackets and hardware.
